Pregnant women can't wear perfume or smell it. Second-hand perfume has a great influence on pregnant women. Many perfumes contain musk, especially some inferior perfumes, with more musk. Once pregnant women are exposed to musk for a long time, it is easy to cause fetal malformation and even abortion. Therefore, during pregnancy, it is best for pregnant women not to wear perfume or use skin care products containing essence, so as not to have a bad influence on the baby. In addition, second-hand perfume is harmful to pregnant women. The pungent smell of perfume may make pregnant women feel dizzy, headache, sore throat, difficulty breathing and other symptoms. Such an environment is not good for the health of pregnant women and their fetuses, so pregnant women should not wear perfume, nor smell second-hand perfume, and stay away from perfume. Perfume may contain chemicals such as musk, which will disturb people's normal endocrine and affect the normal play of hormones. If pregnant women wear perfume or smell perfume for a long time, it may affect their own health and the normal development of the fetus, which may seriously lead to abortion or fetal malformation. In addition, some perfumes are pungent, and pregnant women may have some adverse reactions after spraying, such as dizziness and dyspnea, which are not good for pregnant women and will also affect fetal development. Some perfumes also contain chemicals such as linalool, which will lead to depression of pregnant women and increase the probability of depression of pregnant women. Therefore, during pregnancy, pregnant women should not wear perfume or smell perfume for the health of themselves and their fetuses. Pregnant women should pay attention to avoid toxic and harmful substances, including volatile organic compounds, in their daily lives. In addition, we should pay attention to a light diet, balanced nutrition, rest and relaxation, always pay attention to the physical condition of the fetus and pregnant women, and conduct prenatal examination on time.
